SPECIFICATION forming art of Letters Patent No. 381,065, dated n riilo, I888.

Application filed October 12, 1887. I Serial No. 252,101. (No model.)

Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Folding and Swinging Gates, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to swinging, collap-' sible, or folding gates or guards, and is designed as an improvement on the especial class of 'gates particularly described and fully illustrated in United States Letters Patent No. 369,284, issued to me August 30,1887, and to which particular reference is-hereby made in construing this application.

' The especial object of my invention is to provide a collapsible swinging gate which may in its action automatically lock and unlock I the swinging part thereof, so thatwhen the gate is in extended or closed position the swinging parts are rendered practicallyimniovable, and when the, gate is in folded or open position the swinging parts can be freely operated.

Tothe aforesaid purpose my invention consists, essentially, in providing the swinging parts or section with a trip locking device which is engaged and operated by the moving hanger supporting the gate, and'which is appropriate-to lock the swinging section to the fixed framing when the gate isin extended p0- sition.

In order that my invention may be fully understood, I have illustrated in "the accompanying drawings, and will proceed to describe with reference to the aforesaid patent, the best forms of the device so far devised by me, with the knowledge that such forms admit of constructional modifications.

In the accompanying drawings, Figure 1 is a vertical central sectional view of a portion of a swinging folding gate, as will be under: stood upon referring to the above-cited patent, and which is shown as provided with my triplocking device. The section is taken on line 11 in Fig. 2. Fig. 2 is a top plan view of theparts shownin Fig. 1. Figs-3 and 4 are vertical central sectional views of portions of the gate, and show, respectively, two different forms of my improved locking device.

Referring 'to the drawings, 22is the fixed 35 framing, having the, track 20 for the roller =hang'er'17 to run on. This hanger consists in a track having the wheels 18, and provided with the. anti-friction rolls 19. The, connecting-rod16 is designed to support a gateswung from below, as shown in the aforesaid patent.

The lever-arm is forced upward, so as to unlock, by virtue of the trip or pin 40, which reciprocates vertically through the perforations 45 and 46, formed in the flange 25 and the shelf 26, respectively, being forced upward by the part 44 of the hanger 17 striking the foot of the trip and sliding thereunder. The loose trip-pins 40 in Figs.3 and 4 are formed with collars 47, to

prevent them from dropping through the openings 45 and 46.

In the construction shown in Fig. 4 the lever-arm is a flat spring-strip secured at one end by the screws 48, while the free end of the strip has an eye in which is suspended the head of the latch or plug 41. The resiliency of the strip tends to press the latch into locking engagement with the slot 43, and whenever the hanger is out of engagement with the foot of the trip 40 this locked position will be assumed. When the trip 40 is pushed up by the hanger, the spring 35 will be forced into the position shown in Fig. 4, thereby unlocking the swinging portion from the fixed and allowing the former to be free.

The locking devices are each shown as cov: ered by the casing orhousing 49, which screens the parts from dirt. I

Having th us described my invention, I claim as new and desire to secure by Letters Patent- 1.
